To (2Z1 whom it may :20am

Be it known that, I, SYLvEsTxmNEL-soN, a citizen of the United States of Amer'iea, residing at, Detroit, in the county of Vif'oyne and State of li'iioliigun, have invented c 1'- tain new and useful Improvemeiits in AXle- Dies, of which the following is a specification, reference being had therein to the so compenying drawings.- I i This invention relates to dies for produc ing axles of that type-used inloomieciion with automobiles and other vehicles, the axles having spring memes and the ends bifurcated or forkecii oeoommodate the knuckles of steering wheels. 5 1

The primary object of 'mvrinvention is to provide PGSiiiP/E and reliable-mews, in a manner as hereinafter eefgforth for expeditiously zinc eeonomially producing axles of the above type mini-means including in strumeni-ality 5mg, punching anti bending the ends axle look whereby it is pr o etieail for installation in connection Wibd parts of a Vehicle.

A further object of this invention to provide strong and durable diee by which the ends of on and out to remove the Webs from the need the heads opened to provide )Eorlis am; than the forked ends shaped and finislgecl, thereby ermiiting of a method of mamifacture bemg carried into effect Whioh insures a rapid production with. a minimum amount waste.

With the above and other objects in View, the invention resiies in the novel construe tion, combination and arrange-mom of parts to be hereinafter speoi oeily Gesoribed and then claimed, am} reference Wiil now behoii to the olmwinge wherein Figure 1 is a perspective View of sepw rated dies designer} for produoing an axle; Fig is a. vertioal longitudinal sectional view of the (lies assembled or closed and ehov ing an no ttiiig tool or header in conneetion iilerewitif, Fig. 3 a cross-seeilonel View of the (lies taken on the line illill of Fig. 2'; Fi 4 is a perspeeeive View of an ie a plan of the dies;

In the drawirn derstazidingiirn generally rles g dies for oarryiiig out the formation of construction. The dies are adapted to confront each other iii a or suitable maiifill for olem'ness in uneni ion, the dies nuvebeen the first two steps in an axle are identical in mated A and B eed theee chine by which il e dies can be moved to and from one another or one of main stationary and the otbei mov Lively The dies; reoi i elevation and the oonii lilting Me at one end anal thereof, are pr ied grooves 1 anal oi ogi' tang 01oz recesses 2 siiicl grooves,

bio rem- 13 or in wilflz, iorigitwiinal e end with recin eh munie-aiion with Arranged in the reoesses 2 and reteirieci iherein by etz elieble 'strips 3 yield'zible 4. These formers are in. the form of slide bloeke and limited in by the end walls of the their movemenis recesses Tne inner ends of the formers are proviiled with sockets 5 longitfidinallyaliniiig with bores 6 in said dies and said bores and sockets 5 accommodate coiled compression. springs 7 era 42 normally at the forward onois of 53 dies. The confronting sides of "be formers i are provided with. 1011, me

o th ioi'es i 2 rear ends of the dies and the ends of the grooves are eniarged at 9 and 10 for a, purpose that, will presently appear, Theiorwonl ends of the grooves are also ei'ilargocl' as at 11 and the grooves 1 and 8 cooperate in supporting an axle blank 12 between the dies A and whereby the first; step iii the o oei'aiion of p'roduoin an axle oerrbe safely taken. An axle blank: 1? is oi -appeal to be frictioimlly held by the Walls of the grooves l and 8 when the dies in of the blank pm i ling from the forward enols of the (lies, on upsetting tool or header 13 is brought into e zrxgagflnoxfi with of the blank This tool 11s b Figs. 1. and has; reee en of the blank, and as said tool is brought into action, the protrudingend of the blank is upset andehapeal in the enlarged. ends 9 of the grooves 8 and the recess 14 of said tool. Besides Que outer end of the blank being shaped to form a head 10., the blank is upset at the confronting enlarged end 10 which hold the form- 3 grooves 8- 4' Bed and with one end' the (lies re 1 Keene the lower edges v the end and 11 of the grooves 8 and 1 respectively, thereby providing a spring perch (see Fig. 7). As this first operation is performed, the formers 4 slide or yield and to a large extent release the dies of stresses and strains ncurred when upsetting and shapin the axle blank'12. When the dies A and are recesses 17 that the hookshaped head has a shank 18, abill 19, tang 20 and a connecting web 21. These. are fbrmed by pressingflhe material of the head lsinto the confoonting recesses 17 and the colfnecting web 21 is central and longitudinally of the-end of the blank.

The third step or operation is that of. removing the connecting web 21 which is accomplished by punching or cutting the web. Thedies A and B have the rear ends thereof provided with hook-shaped recesses 23 andthe recess of the die A has a punching member 25 that enters an opening 24 in the-die B and removes the connecting web 21 without distorting the blank. With the reicesses 23' formed in the confronting faces .ofi the dies, the walls of said recesses firmly brace the blank while the connecting web thereof is removed.

The next or fourth operation consists of opening the hook-shaped end of the blank to form a fork. This isaccomplished by providing the top of the die B with holders, .one in the form of a block 26 andthe other in the form of a pin 27. It is between the block 26 and the pin 27 that the blank is placed, as best shown "in Fig. 5, the block 26 bracing the shank 18 of the hook-shaped end of the blank. The top of the dieA is provided with a hook opening member 28 that is angularly disposed and adapted to engage the bill 19 of the blank hook, when the dies A and B are brought together. The .hook is opened by bending the shank 18 against and beyond the block 26 and the pin 27 codperates with the block in preventing displacement of the blank during this operation. The blank is now ready for a finvishing and shaping operation and with this shapes the fork. This is shown in Fig. 6

and the operation which takes place is simply that of bending the shank and bill of the hook whereby the bill will aline with the tang and thus form a fork in which the knuckle of a wheel or steering apparatus can be pivotally mounted.

It is thought that the operation and utility of the dies will be apparent without fur ther description, and while I have hereinf used the terms forward and rear, I .desireit to be understood that these terms are used as a matter of convemenoe in describin the invention and that the dies can be use in any desirable position in a press or ma hin emp oy d ionmo ie z t e. d e and the tools associated therewit What I claim as my inventionis I Means for shaping the. end of ,an axle blank, comprising dies having the confront ing faces thereof provided with recesses, yieldable formers slidab e-in the re- .ccsses of said dies, detachable. strips set inthe faces of said dies for retain ng said formers in said recesses, said formers having grooves longitudinally alining. with the grooves of said dies, the grooves of said dies having ends thereof enlarged, a spring in each recess extending into the body of each .die and retainin said formers inan'extende po it on, an from said diesand e06 crating with said formers in upsettin ab ank in the grooves of said formers an said dies whereby said blank is provided with a head and a perch.
